Sub-panel grounds -again

[rlskfoster]

I can confuse the heck out of myself so Here is my questions-

Sub-panel in a detached garage has a 8-2 with ground as its supply. It is wired as 240 volt

So does it need 1) A ground rod driven

2) Seperated grounds and neutrals

3) A covered neutral

4) should an 8-3 with ground have been ran

The garage does have a sidewalk connected to the house. It does have GFCI protected outlets.

Man I have read Article 250 till I"m blue in the face.

I think it needs a grounding conductor to a ground rod. I think the grounds and neutrals can be together in this instance.

Am I wrong. Help me Obi-Wan.

I know this is probably supposed to be easy but I just don't see it enough to be comfortable.

The white should be re identified.

The splice on the red should be nutted not taped.

The ground and neutral should be isolated.

3 wire w/ground should have been run to the panel.

The person who wired the panel should be shot for making such a mess of so few wires.

I think Cramer said one time "separate the ground & neutral anywhere after the first main disconnect". Makes it real simple.

If I quoted that wrong, I apologize.

The paint in the panel is another no-no.

Hi,

It has more than one branch circuit so it requires its own service grounding electrode and conductor. [250-32a] Ideally it should be the steel in the walk between the house and the garage or a metal pipe below grade, but if it's only got a water pipe inside the building available, you need to add a rod.

Remove the green bonding screw. Install a separate ground bus screwed directly to the panel, move the EGC's onto it. Connect the grounding electrode conductor to it and the SGE.

Done.
